380.13.

The area of a circle with a 22 diameter is 380.13. Hope this helps :)

Answer 2

Answer:

379.94 cm² or 380.13 cm²

Step-by-step explanation:

Hello!

Given that the diameter is 22 cm, we can find the radius by dividing the diameter by 2.

Radius = 11cm

The formula to find the area of a circle is $A = \pi r^2$.

• A = area
• π = pi (≈3.14)
• r = radius

We can find the area by plugging in the radius in the equation.

Find the Area

• $A = \pi r^2$
• $A = (3.14)(11)^2$
• $A = (3.14)(121)$
• $A = 379.94$

The area of the circle is 379.94 cm².

If you are using the real value of pi, you would have an answer of 380.13.
